**Official Met Office guidance and supporting model runs point to a maximum of 23 °C on 30 August, with limited upside potential due to persistent cloud, southwest winds, and scattered showers.** Recent developments show heavy rain and thunderstorms clearing eastern England on the 29th, leaving a regime of bright or sunny spells interspersed with isolated, locally heavy showers on the 30th. These conditions, combined with moderate southwesterly flow, are expected to cap daytime heating near or slightly above the seasonal average for late August. Multiple sources converge on a peak of 22–23 °C, explaining the dominant market-implied probabilities for those two outcomes. Forecast uncertainty remains modest but centers on shower timing and exact cloud breaks; stronger insolation could nudge the high toward 24 °C, while more persistent cloud or earlier showers would favor 22 °C. No significant warm-air advection or high-pressure development is anticipated before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 30 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=eglc
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.**Official Met Office guidance and supporting model runs point to a maximum of 23 °C on 30 August, with limited upside potential due to persistent cloud, southwest winds, and scattered showers.**
